Where do cancer cells in humans come from? There's a way to potentially kill cancer cells, and it's simple
There was once such a shocking saying in the circle of friends: Everyone has cancer cells, and everyone may get cancer. Friends with a little medical knowledge can see that the person who said this obviously doesn't know what is going on with cancer cells and getting cancer. However, this sentence has been used by many unscrupulous businesses as a way to promote some so-called The advertising words of "anti-cancer products" also attracted many consumers.
Where does everyone have cancer cells?
If we really want to talk about it from the level of cells, I'm afraid we have to start with the "living" of people. Friends who took biology classes when they were young know that biology teachers often tell us in the first class that as long as a person is alive, the cells in the body will continue to divide, and so on. With the birth of new cells, old cells will decline and die to maintain a virtuous cycle.
However, as the saying goes, there may be "problematic" abnormal cells in everyone's body. The professional saying is that each person has more or less cells that may undergo genetic mutations. These abnormal cells have the potential to become cancer cell potential. Therefore, we can say that everyone may get cancer, but it is wrong to say that everyone has cancer cells.
You know, even abnormal cells are not the same as cancer cells. First of all, our body already has a very well-evolved defense mechanism. Under normal circumstances, this mechanism will automatically check whether abnormal mutations have occurred in cells. If it occurs, it will try to repair these mutations by itself. It will automatically activate a powerful tumor suppressor gene p53, and then start the cell self-destruction program, and make abnormal cells die through various ways.
Secondly, even if cancer cells are actually born, they will be "targeted" by immune cells. Immune cells are like the police, tracking the movement of cancer cells at all times. If your immune system is functioning normally, immune cells will successfully treat cancer cells Cells beat and knock them out of the body. Of course, if your immune system is not functioning normally, for example, when you are old, immune cells will also "retire". At this time, if cancer cells come back, the body may not be able to resist, and it will slowly develop into cancer.
Perhaps many people think that China is a country with a high incidence of cancer, but in fact, the incidence of cancer in China is still ranked around 70th in the world, and the places with a high incidence of cancer are all developed countries, such as Denmark, which ranks first, and Denmark, which ranks second France, Australia, Belgium, etc., and these countries all have a common feature, that is, their average life expectancy is also in the forefront of the world, so age has always been an important factor in the incidence of cancer. Generally speaking, regardless of men and women, the incidence of cancer will rise sharply after the age of 50.
However, although the incidence of cancer in China is not too high, there are indeed many hidden dangers of cancer around us. Take smoking as an example, one puff of a cigarette can bring 78 kinds of definite carcinogens, which will lead to the death of lung cells. When there is cell death, new cells will be produced at the same time, and lung cells will continue to divide new cells to repair the lungs. More cell division increases the possibility of cell mutation, which also increases the probability of the birth of cancer cells. Coupled with the addition of those carcinogens, smokers are prone to lung cancer.
Exercise May Kill Cancer Cells
From the beginning to the end, I believe everyone can find that the key to killing cancer cells is whether the human immune system is strong or not. Some foreign researchers published studies in authoritative academic journals. They found that in mouse experiments, exercise can directly shrink tumors, and mice that persist in exercise have a much stronger immune system than mice that do not exercise. Later, more studies have shown that exercise can stimulate the body's immune system, activate more immune cells, and continuously improve the body's immunity. Therefore, since we cannot change the growth of age, we can only use these additional means of exercise. Delay the decline of immunity and prevent the occurrence of cancer.
Therefore, whether it is from the perspective of cancer prevention, or from the perspective of promoting skeletal muscle growth, improving blood circulation, improving physical adaptability, stretching the body and mind, cultivating sentiment, and relieving tension, exercise is obviously beneficial to our body There are a lot of benefits, so in order to stay healthy and stay away from cancer cells, the whole family may wish to exercise together.
